History Tools for Collaborative Visualization

Ali Sarvghad, Melanie Tory

In the context of collaborative data visualization and analysis, history tools can play an important role. We present a compilation that characterizes usersʼ probable objectives when using history tools for collaborative work, as well as operations commonly performed on histories. We further characterize user objectives according to the likely time/space setting in which they would be used, and whether they are likely to be used by individuals, groups, or both. We conclude by compiling a list of design and implementation challenges and research questions that need to be discussed and investigated in order to make history tools adequately support collaborative visualization activities.
